Step 1. Launch Splash Window
After you mount or insert the disk with Veeam ONE installation image, Autorun will open a splash screen with installation options. On the splash window click Upgrade.
If Autorun is not available or disabled, run the Setup.exe file from the installation image or disk.
The installer will verify the version of .NET Framework that is currently installed on the machine. If the required version is not found, the installer will prompt to automatically install .NET Framework software that is included with the Veeam ONE installer. When the installation of .NET Framework is complete, you can proceed with Veeam ONE installation.
